The R7 Dunajská Lužná – Holice Section starts between the municipality of Dunajská Lužná and the town of Šamorín at the elevated “Dunajská Lužná” crossing. The entire Section runs along the left side of the I/63 road and ends at the elevated “Holice”.

Construction and operation of this section of expressway will exclude transit traffic from the territory of surrounding villages and improve the impact of traffic on people and the environment.

At ca. km 9,000 near the site called Tárnoki, an ecoduct is designed to ensure the possibility of crossing over R7 for migrating wildlife.
